Expandable Luggage

ABSTRACT

An expandable luggage includes a luggage body, a luggage cover, a secondary cover and an extension fabric connected between the secondary cover and the luggage cover through second zippers. The secondary cover has an outer flange. The luggage cover has an inner flange. The inner flange engages with the outer flange. Thus, when the secondary cover is extended to expand the inner space of the luggage body, the extension fabric can be protected to prevent the extension fabric from being damaged so that the articles in the luggage won&#39;t be stolen.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an expandable luggage, and moreparticularly, to an expandable luggage which can expand or reduce itssize and is durable to prevent the luggage from being damaged.

2. Description of the Prior Art

As shown in FIG. 1 and FIG. 2, a conventional luggage can change thesize of the luggage body. The luggage comprises a luggage body 1, aluggage cover 2 having a first zipper 3 and an extension fabric 5between the first zipper 3 and the luggage cover 2. Both sides of theextension fabric 5 are provided with second zippers 4, respectively. Asshown in FIG. 1, when the user wants a small-sized luggage, the secondzippers 4 are zipped to hide the extension fabric 5 so as to shorten thedistance of the luggage body 1 and the luggage cover 2. As shown in FIG.2, when the user wants to expand the size of the luggage, the secondzippers 4 are unzipped to expose the extension fabric 5 so as tolengthen the distance of the luggage body 1 and the luggage cover 2. Theforegoing structure has the following shortcomings.

1. The extension fabric 5 is made of a soft material and its strength isnot good so the extension fabric 5 may uneven.

2. The thief can cut the extension fabric 5 to steal the articles in theluggage easily.

3. Because the extension fabric 5 is soft, the luggage body 1 may bedeformed.

This causes the luggage wheels to run unstably.

4. As shown in FIG. 3, when the luggage is dragged with two wheels andthe luggage cover 2 is filled with some articles to have a certainweight, the luggage cover 2 may slide downward to cause deformation ofthe luggage.

Accordingly, the present invention intends to provide an expandableluggage for improving the shortcomings mentioned above.

SUMMARY OF THE INVENTION

The primary object of the present invention is to provide an expandableluggage. The expandable luggage comprises a luggage body, a luggagecover, a secondary cover, and an extension fabric between the secondarycover and the luggage cover. Two sides of the extension fabric areprovided with second zippers to connect with the luggage cover and thesecondary cover. The luggage cover has an inner flange. The secondarycover has an outer flange. The inner flange engages with the outerflange. When the user wants to reduce the size of the luggage, a portionof the secondary cover is retracted in the luggage cover. When the userwants to expand the size of the luggage, the secondary cover can beextended outward and the extension fabric is still protected by theluggage cover to prevent the extension fabric from being damaged and toprevent the articles in the luggage from being stolen. The inner flangeengages with the outer flange so that the secondary cover and theluggage cover are connected together to form a durable luggage.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Embodiments of the present invention will now be described, by way ofexample only, with reference to the accompanying drawings.

As shown in FIG. 4, FIG. 5 and FIG. 6, the present invention comprises aluggage body 10 having a first zipper 11 and a luggage cover 12. Oneside of the luggage cover 12 is provided with a secondary cover 14. Anextension fabric 20 is provided between the secondary cover 14 and theluggage cover 12. Two sides of the extension fabric 20 are provided withsecond zippers 21 to connect with the luggage cover 12 and the secondarycover 14. The secondary cover 14 has an outer flange 15 around aperiphery thereof. The luggage cover 12 has an inner flange 13 around aperiphery thereof. The outer flange 15 of the secondary cover 14 ismounted in the luggage cover 12 so that the inner flange 13 of theluggage cover 12 engages with the outer flange 15 of the secondary cover14.

According to the aforesaid structure, the functions and effects of thepresent invention are descried in detail hereinafter. As shown in FIG.5, when the user wants to expand the space between the luggage body 10and the secondary cover 14, the second zippers 21 are unzipped to extend(unfold) the extension fabric 20 and the secondary cover 14 is extendedoutward from the luggage cover 12, such that the size of the luggage isincreased. When the user wants to reduce the inner space of the luggagebody 10, the secondary zippers 21 are zipped to shorten (fold) theextension fabric 20, such that a portion of the secondary cover 14 isreceived in the luggage cover 12 to reduce its size. Accordingly, thepresent invention has the following effects and advantages.

1. As shown in FIG. 5, when the size of the luggage is expanded and theextension fabric 20 is extended, the extension fabric 20 is stillcovered by the luggage cover 12 so that the extension fabric 20 won't bedamaged and the articles in the luggage won't be stolen.

2. As shown in FIG. 5, when the size of the luggage is expanded and thesecondary cover 14 is extended outward, the outer flange 15 is stoppedby the inner flange 13 of the luggage cover 12 to keep the connectionstate. Thus, the luggage is durable and won't have the uneven problem.Besides, the luggage cover 12 and the secondary cover 14 are connectedstably. The luggage body 10 won't be deformed and the luggage wheels canrun smoothly and stably.

3. As shown in FIG. 6, when the size of the luggage is reduced, thesecondary cover 14 is retracted in the luggage cover 12 to form a dualstructure at their connecting position so as to enhance the strength ofthe luggage.

Although particular embodiments of the present invention have beendescribed in detail for purposes of illustration, various modificationsand enhancements may be made without departing from the spirit and scopeof the present invention. Accordingly, the present invention is not tobe limited except as by the appended claims.

What is claimed is:
 1. An expandable luggage, comprising a luggage bodyhaving a first zipper and a luggage cover, one side of the luggage coverbeing provided with a secondary cover, an extension fabric beingprovided between the secondary cover and the luggage cover, two sides ofthe extension fabric being provided with second zippers to connect withthe luggage cover and the secondary cover, the secondary cover having anouter flange around a periphery thereof, the luggage cover having aninner flange around a periphery thereof, the outer flange of thesecondary cover being mounted in the luggage cover; wherein, when a userwants to reduce the size of the luggage, a portion of the secondarycover is retracted in the luggage cover and the second zippers arezipped to fold the extension fabric and to position the secondary cover;when the user wants to expand the size of the luggage, the secondzippers are unzipped to extend the extension fabric and the outer flangeof the secondary cover engages with the inner flange of the luggagecover to enhance connection of the secondary cover and the luggagecover.
